stmmac_verify_args(9)

💖 stmmac_verify_args(9) — the Kernel API Manual glow-up 💖

okay so bestie, we're in the Kernel API Manual today, and the star of the show is stmmac_verify_args. it's giving "quiet little sanity-checker that keeps the whole driver from falling apart" and honestly? iconic. ✨

---

✨ NAME ✨

stmmac_verify_args — verify the driver parameters.

like, it's the vibe check for your driver params. no cap. 🫶

---

🦋 SYNOPSIS 🦋

void stmmac_verify_args (void );

that's it. that's the whole signature. she's minimal, she's void, she's serving lewk. 💅

---

🎀 ARGUMENTS 🎀

• void — no arguments. nothing. zero. the void is voiding. 🙈

honestly a whole mood — she takes nothing and still gets the job done. main character energy fr fr.

---

🌸 DESCRIPTION 🌸

so here's the tea: stmmac_verify_args checks the driver parameters and sets a default in case of errors.

that's the whole thing bestie — it's the little safety net. you hand it nothing, it looks at the params, and if something's cooked it quietly drops in a default so everything keeps slaying instead of exploding. lowkey the most responsible function in the whole file and nobody ever thanks her. 😭

no arguments in, no return value out — she works purely in side effects. the parameters get verified and the defaults get set, periodt. 🔥

and that's the whole page, bestie 💜 this cutie dropped from ./drivers/net/ethernet/stmicro... back in October 2026, and yes she's still signed stmmac_verify_args(9) at the bottom like the little legend she is. mwah. 💋🎀
